Mobile Device Synchronization via UDP Multicast and mDNS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling mobile devices in mass spectator events lack comprehensive multimedia interaction, failing to enhance spectator experiences by not utilizing the full potential of personal devices for synchronized and coordinated audio/visual elements.
Innovation Solution
A method using a controller application to transmit commands via UDP and mDNS protocols, allowing mobile devices to receive and execute synchronized commands, filter based on location, and integrate multimedia content, including MIDI control, to coordinate device actions across a venue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multicast UDP protocol is used to transmit commands to mobile devices, then synchronization efficiency is improved, but compatibility with mobile devices is worsened because a portion of mobile electronic devices does not support multicast
Solution Approach 1:
The patent introduces mDNS (multicast DNS) as an intermediary protocol to bridge the gap between multicast-capable and multicast-unsupported mobile devices. The system transmits commands via mDNS queries and responses, allowing universal compatibility while maintaining efficient synchronized control across all device types in the venue.
2Reliability
If traditional venue speakers and screens are used, then audio and visual effects are provided, but spectator multimedia interaction is limited
Solution Approach 1:
The patent transforms spectators' personal mobile devices into multi-functional venue equipment. Each device can simultaneously serve as a display screen, speaker, camera, and interaction terminal, enabling diverse multimedia interactions including taking photos, receiving notifications, and participating in venue-wide activities while maintaining reliable audio and visual output.
3Ease of operation
If mobile devices are controlled individually, then device autonomy is maintained, but coordinated control across the venue is difficult to achieve
Solution Approach 1:
The patent implements preliminary pairing and connection between mobile devices and the venue system before the event begins. Devices are pre-configured with venue identifiers and communication parameters, allowing them to autonomely join the coordinated control network upon arrival without requiring manual setup or complex real-time configuration during the event.
